Atomic outflow rate as a function of the SFR, for both individual detections of broad wings (circles) and from line stacking of the whole sample and of the sources with non-detected outflow (big and small squares, respectively). The pink and violet lines are the best-fit relations between molecular outflow rate and SFR for local AGN hosts and star-forming/starburst galaxies by Fluetsch et al. (2019), respectively, while the shaded regions are the corresponding uncertainties. The solid gray line with the shaded area represents a linear fit to the DGS galaxies with individual outflow detections and its uncertainty, respectively. The dashed line reports the 1:1 relation. We also show the results from [CII] stacking of z ≳ 5 SFGs by Gallerani et al. (2018; hexagon) and Ginolfi et al. (2020; diamond). All markers are color-coded for their mass-loading factors.
